AI Technical Summary
Technical Problem
When the size of existing surgical stapler tool components is reduced to 10 mm or less, the structural strength of the molded components decreases, affecting the normal performance of cutting and suturing operations.
Method used
Design a molding component in which the molding body and the cover are integrally molded, and process grooves and slots are provided to form a closed cavity and a T-slot, thereby improving processing convenience and enhancing structural strength.
Benefits of technology
In surgical cutting and suturing procedures, the strength of the molded components meets the requirements, and the deformation is less than 0.1 mm, ensuring the stability of the fastener molding and the surgical outcome.

Abstract
The application provides a forming member and a preparation method thereof, and the forming member is used for forming a fastener in a surgical anastomosis operation, and comprises a forming body and a cover which are integrally formed, a sealed cavity between the forming body and the cover, and a slot which penetrates at least part of the forming body in an axial direction and communicates with the sealed cavity from one side of the forming body, wherein the forming member further comprises a process slot which penetrates at least part of the cover and communicates with the sealed cavity from one side of the cover, and / or the process slot is located at the distal end of the slot and does not communicate with the sealed cavity. In the application, the forming body and the cover are integrated, and the process slot is selectively arranged at different positions on the forming body and / or the cover, so that the process of integrally forming the forming body and the cover is facilitated, and meanwhile, the strength of the integrated forming member formed by the forming body and the cover can meet the strength requirement in the surgical cutting and suturing operation.
